Do you _really_ need to do this in place? If not, the simplest answer
is probably:
>>> x = ['test\n', test2\n', 'test3\n']
>>> x = [s.rstrip('\n') for s in x]
And if what you really want to do is strip off all trailing whitespace
(tabs, spaces, and newlines), then:
>>> x = [s.rstrip() for s in x]
A quick test of 1,000,000 strings of length 27 took less than 0.2
seconds on my PC. Efficiency isn't really much of an issue for most
data sets.
